I recently installed did a clean install (Feb 8th snap) and noticed that www/horde breaks on new installs if you choose a PostgreSQL backend. After some poking around it seems the MDB2-pgsql driver is missing. Previously (php-5.2) just using stock pear-MDB2 worked. I created a port for pear-MDB2-pgsql and with this installed everything works as it previously did. diff is attached.
